new Crustacea from Devon and Cornwall. 288 



pair also resemble in some respects those of the species 

 referred to, but differ somewhat in form and armature ; the 

 primary joints terminate in a narrower apex, and on the 

 inner margin there are short and subeqnal setae and two 

 slender terminal seta? of unequal length ; the space that sepa- 

 rates this pair of setae from the nearest of the other three is 

 distinctly wider than that which separates these three from 

 one another ; the secondary joints are subovate and nearly 

 twice as long as broad ; the outside edge is nearly straight, 

 but the inner is broadly convex ; a seta springs from near 

 the middle of the outer margin and four from the angularly 

 rounded extremity of the joint. 



Furcal joints short. 



Hab. Dredged outside the harbour at Fowey, Cornwall, 

 May 12th, 1903; not common. No males were observed. 



Stenhelia longirostris, sp. n. 



The form we describe under this name was dredged at 

 Salcombe in 1875. It is not unlike S. reflexa, T. Scott, in 

 its general appearance and in the structure of some of its 

 appendages ; it is, however, a smaller species, the specimen 

 from which the description was prepared measured about 

 •88 mm. (Jg of an inch) in length. Body subcylindrical, 

 with the forehead produced into an elongated and rather 

 slender rostrum. The first joint of the eight-jointed an- 

 tennules in the female is slightly longer than the second and 

 nearly twice as long as the third joint; the fourth, which is 

 also rather longer than the third, has the upper distal angle 

 produced forward to near the end of the following joint to 

 form the base of a long sensory filament ; the fifth, sixth, and 

 seventh joints are small and nearly equal in length, while the 

 last is about twice the length of the preceding one. The 

 formula shows approximately the proportional lengths of all 

 the joints —

The three-jointed outer ramus of the second antennas is of 

 moderate length. 



The first joint of the second maxillipeds bears two mode- 

 rately long setse on the inner aspect of the distal end ; second 

 joint narrow, subcylindrical, and furnished with a longitudinal 

 row of spinules on its inner aspect, and a small seta near the 

 middle and another near the end of the inner margin ; 

 terminal claw slender and moderately elongated. In the
